OILING DEVICE FOR CLAY BARS.

Application filed July 30, 1915.

To all w kom it may concern:

Be it known that I, HOWARD K. KING, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia, State ofPennsylvania, have invented a new and useful Oiling Device for ClayBars, of which the following is a specification.

My invention relates to improvements in oiling device for oiling thetraveling clay bars, and is especially applicable to brick machinesemploying the wire side cutter. In such machines it is deemed desirableto have the bottom and one side of the bar lubricated before the same isacted upon by the wires.

The object is to provide improved and eliicient means for supplyingexactly the right amount of lubrication to said surfaces without wasteof the lubricant and without eX- posing the supply of oil to foreignsubstances.

Referring to the drawings, which illustrate merely by way of example,suitable means for the embodiment of my inven tion- Figure 1 is a sideelevation showing my improved mechanism. Fig. 2 is an end elevation ofsame. Fig. 3 is a section on line SW3 of Fig. 2. Fig. 4 is a section online 4-4 of Fig. 3. Fig. 5 is a detail of parts shown in Fig. 1 on anenlarged scale. Fig. 6 is a section on line 6-6 of Fig. Fig. 7 is asection on line 7 7 of Fig. 5.

Similar numerals refer to similar parts throughout the several views.

The oil reservoir 11 is suitably located at an elevation above the pathof travel of the clay bar. Suitable conducting pipes 12 and 13 areconnected with this reservoir. Plate 14 is mounted on the reel carriageor hous- ,ing 10 and travels therewith. This plate 14 is recessed as at15, and is provided with bevel edges adapted to cooperate withcorresponding bevel edges of the plate 16, which is bolted thereto;there being clamped between said plates a suitable porous material 17such as felt. The longitudinal margins of this felt are bent over andclamped between the sides of plate 14 and the lugs 18 of plate 16thereby forming a tight seal all around the margin of the felt 17. Theribs 19 are somewhat similar in construction to 18, but ending justshort of the middle in space or chamber 2O which is formed in the bodyof plate 16 beneath said felt 15. These ribs serve to support the feltin substantially Specification of Letters Patent.

horizontal position. The chamber 20 is connected to the pipe 13 by whichit is served with oil from the tank or reservoir 11. The pressure orsupply of the oil delivered from reservoir 11 to chamber 20 iscontrolled by a suitable needle valve 22, so that in operation asuflicient pressure of oil is delivered to chamber 20, to float or pressthe felt surface gently against the under surface of the moving claybar, and just suflicient oil will ooze through the felt to giveefficient lubrication to said surface. The important feature in thisarrangement is that by the proper adjustment of the needle valve therequired pressure of oil in chamber 20 is maintained, and consequentlythe required amount of oil is delivered through the felt to the clay barwithout waste and also without undue exposure of the oil or the oilingsurface.

For oiling a side surface of the bar I have provided a similar deviceillustrated in Figs. 5, 6 and 7 in which the cylinder 24 is mounted in avertical vposition being closed at the top and bottom and provided alongone side with a series of apertures 25. Over this portion of thecylinder which is provided with the apertures 25, is clamped the body 26of porous material, such as felt, between said cylinder and the sideplate 27, which side plate is recessed at 28 so that the outer surfaceof felt is made to project slightly beyond the surface of plate 27 sothat as the bar moves along against said surface it will engage the felt26. rlhe oil is delivered to cylinder 24 through the pipe 12 fromreservoir 11; the supply being controlled by the needle valve 29. Byproperly locating and proportioning the apertures 25, and by properlycontrolling the supply of oil by the valve 29, the required pressure ofoil will be maintained in cylinder 24 and will be supplied through thefelt 26 to the side surface of the clay bar 23.

In the embodiment of my invention above described I have given felt asan example of a suitable body which is adapted to give a yieldingpressure against the moving bar and is sufficiently porous or adapted topermit the oil to ooze therethrough to the surface of the bar. It willbe understood however that I do not confine myself to this particularmaterial, as obviously other material or materials or substances may beused with Ysimilar results.

What I claim is yl. An oiling device for clay bars comprising a surfaceof porous material located in the path of travel of the bar, means fordelivering oil to said material, and regulating means for controllingthe pressure of the oil so that the required amount will be deliveredthrough the material to the surface of the bar as the same moves inengagement therewith.

2. An oiling device for clay bars comprising a recessed slide plate, arecessed member clamped thereto, a porous fabric clamped between saidplate and member, forming one side of ka chamber or oil receptacle, itssurface approximately corresponding to the supporting surface of theplate, means for delivering oil to said chamber whereby oil is deliveredthrough the fabric to the clay bar.

3. An oiling device for clay bars comprising arecessed slide plate, arecessed member clampedl thereto, a porous fabric clamped between saidplate and member, forming one side of a chamber or oil receptacle, itssurface approximately corresponding to the supporting surface of theplate, means for delivering` oil to said chamber whereby oil isdelivered through the fabric and the fabric is maintained in engagementwith the moving clay bar.

4. An oiling device foiclay bars comprising a recessed slide plate, arecessed member clamped thereto, a porous fabric clamped between saidplate and member, forming one side of a chamber or oil receptacle, itssurface approximately corresponding to the supporting surface of theplate, means for delivering oil to lsaid chamber whereby oil isdelivered through the fabric and the fabric has a tendency to be liftedslightly above the normal to insure efficient yielding engagement withthe clay bar and whereby undue wear is obviateds 5. An oiling device forclay bars comprising a recessed slide plate, a recessed member clampedthereto, a porous fabric clamped between said plate and member, formingone side of a chamber or oil receptacle, its surface approximatelycorresponding to the supporting surface of the plate, means fordelivering oil to said chamber whereby oil is delivered through thefabric to the clay bar, and means for regulating the pressure of the oilto the required supply.

6. Anoiling device for briclr machines comprising a slide plate having anarrow slot or recess in its face extending transverse the path oftravel of the clay bar, a porous material projecting into or throughsaidrecess adapted to have yielding engagement with the surface of theclay bar, means whereby oil is delivered to said porous material adaptedto ooze therethrough to the clay bar, and means for controlling orregulating said oil delivery.
